I have multiple NCD I2C devices connected together on a single I2C bus connected to the NCD Arduino MKR I2C interface shield.
I am having intermittent communications to the devices and am wondering if I have the I2C pull-up jumpers set correctly.
Each of the NCD modules has a pair of pull-ups. The documentation for some of the modules indicates to place the jumpers on if the master I2C controller does not have them. The documentation for the MKR board does not indicate that it has the pull-up resistors or not.
Do I enable the pull-up resistors on the last connected module on the bus, for each module or none of them?
Appreciate your assistance, thank you!
